I'm also a traditionalist, and prefer 2-channel stereo.
I have a dual monoblock amplifier by B&K, which is probably 10-15 years old. It puts out 240 watts per channel, and is as close to dual monos as you can get. There are actually 2 amplifiers inside the shell, one for each channel, which gives awesome seperation and a very vivid sound stage.
I also have a B&K preamp/tuner combination.
For speakers, I have a pair of Paradigm S4s and a matched Paradigm subwoofer.
Input is just a Sony CD/DVD player. I have an old Duel turntable, but it has a ground issue, an is currently stored in the attic.
I chose all my components based on value. There are many more high-end options, but B&K offers the best sound for the $$, and so does Paradigm. BTW, NAD amplifiers also provide very good "warm" sound, a lot like wthe older tube amplifiers even though they are solid state.
I have about $800 in the Amp & Preamp, and about $3,000 in the speakers. But the sound I have is comparable to systems that would cost 4-5 times as much.
There's nothing like putting on Pink Floyd's "Shine on you Crazy Diamond" closing your eyes, and getting lost in the music. The sound stage is so clear and wide, that you could swear each instrument is coming from a slightly different angle.
